It seemed like a good way to drum up excitement: "Let's start the 10 day countdown with a little couture @maisonvalentino #theprismaticworldtour," Katy Perry captioned this Instagram when she posted it yesterday. We were into the stunt before we even realized it was just the first in a series. Who doesn't want to sneak a peek at her tour outfits and the crazy elaborate way these couture sketches are presented? Like, does this one come with its own inspirational mantra ("Happiness is like a butterfly")? (Is that normal?)

Then, Katy posted this, with the caption "9 DAYS TILL #THEPRISMATICWORLDTOUR Oh hay, @roberto_cavalli 👗👗👗," not only displaying a fine command of emoji but also suggesting that this is, perhaps, a daily countdown sort of thing (!!):

Naturally, we'll be stalking her Instagram for the next several days before her Prismatic world tour kicks off, looking to see more of these things. It's like a chocolate advent calendar but FASHION. How could you not like it?

What do you think of Katy's tour costumes? What would you like to see her wearing? Let us know in the comments!
